sounds cool. i'm looking forward to test it.
theoretically the fertility is proportional to the water contained in the 15x15
surrounding square so you have 31*31=961 values making the most common max of
15*31=465=0.5*max (max. fertility at a straight coast) appear too dimm.
i'd not treat islands specially as this might interfere with future features
like carrying seeds but rather clip the fertility-indicator at 400 or shift
colors from 400 to 800.
Algorithm:
f=000..400: r=0, g=1, b=0, a=f/400/*.25
f=400..800: r=(f-400)/400*.8, g=1, b=(f-400)/400*.8, a=0.25
f=800..961: r=.8, g=1, b=.8, a=0.25
Do you represent fertility in water, too? Guess the formula was a bit more
complicated there but i'd like to see fertility there as i barely know
algues-growth at all.

P.S.: the fertility computation should be of order widthMap*heightMap*31 as you
can count water line by line and store those line-fertilities.
